Answer:
A piece of Jewelry costs $4.5 and a hair accessory costs $1.5.
Step-by-step explanation:
Let the price of a piece of jewelry is $x and that of a piece of hair accessories is $y.
So, from the given conditions we can write two different equations as
5x + 8y = 34.5 ............ (1) and
2x + 16y = 33 ............... (2)
Now, solving the equations (1) and (2) we get
2x + 2(34.5 - 5x) = 33
⇒ 8x = 36
⇒ x = $4.5
Again, from the equation (2) we can write
2(4.5) + 16y = 33
⇒ 16y = 24
⇒ y = $1.5
Therefore, a piece of Jewelry costs $4.5 and a hair accessory costs $1.5. (Answer)

Answer:
105 miles
Step-by-step explanation:
The question seeks to know the number of miles traveled by Tiera given that she received a certain amount of money in payment.
The total amount of money she received is $147. She receives $7 for every 5 miles traveled. The number of 5 miles traveled is calculated as 147/7 = 21
This means she traveled 5 miles 21 times.
Thus, the total number of miles she had traveled would be 21 * 5 = 105 miles in total
Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-4) = -1......( perpendicular to a line with a slope of 4)</span>
<span>a= 1/4</span>
: y = (1/4)x + b
<span>
the line that passes through (8, -1) : -1 = (1/4)(8)+b
b =-3
the equation is : y = (1/4)x-3</span>
